Same/different discrimination learning with trial-unique stimuli

A long-standing issue in same/different discrimination learning concerns the possible role of individual stimulus memory through repeated presentation. The aim of eliminating any effect of repetition prompted us to devise a new method for generating trial-unique stimuli. These stimuli were arrays of 16 mosaics, each containing 16 cells, which could be filled with 16 possible luminance levels. In Experiment 1, we successfully trained 4 pigeons with these trial-unique stimuli in a two-alternative forced choice same/different discrimination task to 80% correct-choice performance. We later conducted two tests that explored the nature of this discrimination and suggested that pigeons compared the mosaics in the arrays on the basis of their spatial configurations, not on the basis of lower level perceptual properties. In Experiment 2, college students responded similarly to the same sequence of training and testing. Our results suggest that pigeons and people may use similar mechanisms in relational discrimination learning.     

Social and racial correlates of Russian roulette

The epidemiology of a neglected form of suicidal behavior, Russian roulette, is addressed. Also tested is an explanation of racial differences based on the opportunity theory of deviant behavior related to the availability of revolvers, necessary weapons with which to play Russian roulette. Data refer to 15 cases of Russian roulette found through a search of the medical examiner's suicide files (N = 1,412) and 75 matched controls who suicided by a gunshot to the head. The results support an opportunity perspective: 80% of the Russian roulette victims were African American compared to 30.7% of the controls. Further, among the controls, Blacks were three times more likely than Whites to use revolvers in suicides, a pattern indicating Blacks' greater access to revolvers. Russian roulette victims were entirely male, significantly younger, and less apt to be married than the control group.     

Online professionalism: social media, social contracts, trust, and medicine

The AMA Council on Ethical and Judicial Affairs (CEJA) has initiated an important discussion on medical professionalism and the use of social media by issuing thoughtful and practical guidance for physicians and medical students. The implications of online activities for trust in the profession, as well as for trust between patient and doctor, however, will need further exploration as digital life expands and evolves.     

How much of a loss is the loss of self? Understanding Vygotsky from a social therapeutic perspective and vice versa

Using the example of Fred Newman’s social therapy, a methodology that works with the human capability of growing as social units, the contemporary self is explored as an impediment to human development and learning. Following Karl Marx in political philosophy and Lev Vygotsky in child psychology, it is the group/the collective/the mass that engages in developmental activity. In losing the self, we gain the opportunity to create collectivity and in that process come to sense the social-relational-collective quality of creativity and development. By getting rid of the self, we are more able to see the group, which is—developmentally speaking—the important unit of study. In this article I share the role that Marx, Vygotsky and Ludwig Wittgenstein played in the creation of this understanding and critical practice.     

The dimensional nature of same-different discrimination behavior in pigeons

We studied the dimensional nature of same-different discrimination behavior in pigeons. Birds first learned to discriminate between simultaneously presented displays of 16 identical items (Same arrays) and 16 nonidentical items (Different arrays), conditional on the color of the background. After discrimination mastery, we tested the birds with Mixture arrays comprising both identical and nonidentical items. Accuracy increased and reaction time decreased as the disparity in entropy (a measure of variability) between the arrays increased. As well, within each entropy disparity level, lower entropy values were more discriminable than higher entropy values. These results accord with a logarithmic relation between entropy and discriminative behavior and, thus, with the idea that the discrimination of Same from Different arrays follows Weber's Law.     

The Role of Death Qualification in Venirepersons' Attitudes Toward the Insanity Defense1

Three hundred venirepersons from the 12^th Judicial Circuit in Florida completed a booklet of stimulus materials that contained the following: one question that specified participants' level of support for the death penalty; one Witt death‐qualification question; a case scenario that included a summary of the guilt and penalty phases of a capital case; verdict and sentencing preferences; a 16‐item measure that required participants to rate their receptiveness to the insanity defense on a 6‐point Likert scale; and standard demographic questions. Results indicated that death‐qualified venirepersons, when compared to excludables, were more likely to endorse certain insanity myths, find the defendant guilty, and sentence the defendant to death. Legal implications are discussed.
